ContentTypeCollection ctCol;
if (searchInSiteHierarchy)
{
    ctCol = web.AvailableContentTypes;
}
else
{
    ctCol = web.ContentTypes;
}

web.Context.Load(ctCol);
web.Context.ExecuteQueryRetry();
foreach (var item in ctCol)
{
    if (item.Id.StringValue.StartsWith(contentTypeId, StringComparison.OrdinalIgnoreCase))
